Inventor: NODA JUICHI
IPC: G02B6/30
Filed: 1989-03-30
Abstract: PURPOSE:To improve the latitude for connection of the optical waveguide and an optical fiber by forming one end part of the single mode optical waveguide to a horn shape which expands gradually in section toward one end face and connecting the end face of the single mode optical fiber to the one end face of the single mode optical waveguide. CONSTITUTION:The optical waveguide element 110 of single mode is formed of a quartz glass material and has the structure in which the optical waveguide 112 is formed on a substrate 111. The left end part of the optical waveguide 112 is formed as the tapered optical waveguide 112a. This tapered optical waveguide 112a has the horn shape which expands gradually in the width toward the left end face. On the other hand, the optical fiber 120 of the single mode has a clad 121 and a core 122 and the right end of this optical fiber 120 is connected to the left end face of the tapered optical waveguide 112a. Since there is the tapered optical waveguide 112a having the wide connecting end face, the allowance for connection in parallel with the plane of the substrate 111 is greatly improved.

Abstract: PURPOSE:To ensure judgement of half-wave discharging condition of a discharge lamp and protect a self-exciting inverter by suppressing oscillating action in accordance with specific combination of the output conditions of a frequency judging circuit and a lamp characteristic judging circuit. CONSTITUTION:A frequency judging circuit SH senses the oscillation frequency of a self-exciting inverter IN as No.1 reference for judgement, and two-value output is emitted in accordance with the sensed oscillation frequency which is either high or low. At the same time, a lamp characteristic judging circuit H senses the lamp current of a discharge lamp l as No. 2 reference for judgement, and two-value output is generated in accordance with the lamp current which is either large or small. On the basis of these two-value outputs from the frequency judging circuit H and lamp characteristic judging circuit LH, a protector circuit HG suppresses the oscillating action of the self-exciting inverter IN when the two-value outputs becomes a specific combination corresponding to the half-wave discharging condition in the final period of the lifetime of discharge lamp l, so as to protect the self-exciting inverter IN against the half-wave discharging condition in the final period of the lifetime of discharge lamp l.

Title: Compander circuit
Inventor: KIMURA KATSUHARU
IPC: H04B1/64
Filed: 1987-03-30
Abstract: PURPOSE:To prevent a packaging area from being expanded even when the number of components of a circuit is increased, by providing a means which switches the output current of a rectifier to zero or a constant current. CONSTITUTION:A compander circuit is constituted by providing the rectifier and a variable gain cell. In such constitution, assuming V1=0 and V2=Vcc, since transistors(Tr)Q1 and Q6 are turned off, the output current IG of the rectifier goes to zero, and a current to be supplied to the variable gain cell goes to zero, then, the gain of the variable gain cell goes to zero. In other words, the compander circuit is set an OFF state, therefore, the output signal of the compander circuit disappears. Also, assuming V1=Vcc and V2=0, since the TrQ1 is turned on, and Trs Q2, Q7, Q8, and Q9 are turned off, the current IG goes IG=I0, which represents the constant current. And by setting the value of the current I0 at a prescribed value, the compression and expansion characteristic of the compander circuit is eliminated. Namely, the same state as the through state of the compander circuit is generated at this time.
